Moog is the leading producer of synthesizers in the world, I would guess. For every concert i have been too, the staple instruments for the piano player are a hammond B3 organ (with the leslie speaker ofcourse), and one or more Moog brand synthesizers.
Well, we all love the theremin, and Moog just created the first polyphonic theremin. Many have tried, and all but Moog has failed. Apparently, when you put 2 theremins in the same room, they dont work, or you get alot of feedback with eacher, but Moog figured out how to make them work together. Check it out!!
